Sketch the graph for the equation f(x) = x³ – 2x² + x + 1. In the graph, show the local extrema of f(x), the intervals on which the graph of f(x) is concave upward or is downward, and the coordinate of the point of inflection. Sketching only the graph will not giving you the mark. Demonstrate how you get the answer.
